Fallax DMARC Record Generator

Fallax DMARC Record Generator is a browser-based tool that creates a DMARC TXT record for a domain based on user-selected settings such as policy (none, quarantine, reject), reporting addresses, subdomain policy, alignment mode, and report interval. The tool outputs the exact record to publish and explains what each DMARC tag does. It also provides a suggested rollout plan showing how the record changes over time, moving from a monitoring-only policy (p=none) through partial quarantine, full quarantine, and finally reject, to avoid blocking legitimate mail while enforcement increases. The page notes that generated records are built client-side in the browser and are not uploaded or stored. It also links to related Fallax tools: a domain spoofing checker that reads a domain's live SPF, DKIM, and DMARC records, and an email header analyzer that inspects headers of individual messages. The tool addresses common DMARC configuration issues, including missing report addresses, premature enforcement without a rollout, and dependency on existing SPF/DKIM setup. It clarifies that DMARC prevents exact-domain spoofing but does not address lookalike domains or display-name spoofing, for which Fallax offers a separate phishing simulation product.
